Title

Local initialization files' library search paths must contain only absolute paths. (Cat II impact)

Discussion

The library search path environment variable(s) contain a list of directories for the dynamic linker to search to find libraries. If this path includes the current working directory or other relative paths, libraries in these directories may be loaded instead of system libraries. This variable is formatted as a colon-separated list of directories. If there is an empty entry, such as a leading or trailing colon, or two consecutive colons, this is interpreted as the current working directory. Paths starting with a slash (/) are absolute paths.

Check Content

Verify that any PATH variable contained in a user's local initialization files uses only absolute paths. # cat /etc/passwd | cut -f 1,1 -d ":" | xargs -n1 -IUSER sh -c 'egrep -i "LD_LIBRARY_PATH|SHLIB_PATH" ~USER/.*' The PATH variable is a colon-delimited directory list. An empty entry is defined by a leading/trailing colon or two consecutive colons. A relative path is defined as an entry beginning with a character other than a slash (/). If an empty or relative path is defined in the PATH variable, this is a finding.

Fix Text

Edit the user's local initialization file(s) and remove any relative/empty path entry from the library search LIBRARY_PATH and/or SHLIB_PATH variable(s).
